Un-rrnn STATES EDWARD OLATOR, OF WHEELING, WEST VIRGINIA, ASSIGNOB OFONE-HALF- HIS RIGHT TO J. BOONE MGLURE, OF SAME PLACE.

IMPROVEMENT IN MOLDS FOR CASTING WHISTLES.

Specification forming part of Letters Patent No. 127,956, dated June 18,1872; antedated June 4, 1872,

To all whom it may concern.-

7 Be it known that I, EDWARD OLATOR, of the city of Wheeling, in thecounty of Ohio and State of West Virginia, have made the inventionshereinafter described relating to (last Whistles and their Manufacture,of which the following is a specification, reference being had to theaccompanying drawing and the letters of reference thereon.

- My inventions consist, first, of a mold in which whistles ofamouth-piec'e and. a body or bowlthe one being to the other at such anangle that the air, or a sufficient quantity thereof, when blown throughthe mouth-piece will strike against the inside of the part bordering theair-discharge aperture therein at the place of the intersection of themouth-piece and the bowl-are cast from sugar, plaster of Paris, andother suitable materials .upon two cores, so arranged. in the mold thatthe airpassage in the mouth-piece will be formed by one core, and theair-chamber in and throughout the bowl or body and the air-dischargeaperture will be entirely formed by the other; and, second, of thewhistle constructed and produced, as above described, as an improvedarticle of manufacture.

Figure 1 is an elevation of the molds set up for use. Fig. 2 is avertical half-section of the same, the section being taken on the lineas w, Fig. 1, and showing the construction of the mold and thearrangement of the cores therein to produce the whistle. Fig. 3 is anelevation of a complete whistle made according to my improvement. Fig. 4is a half-section of the same taken lengthwise of the whistle, andshowing its acoustic construction. 1

Like letters of reference indicate like parts.

A and B are two parts,which together have the form of the exterior ofthe whistle. C is another and the base part. The part A is provided witha core, D, to form the air-passage E in the mouth-piece F of thewhistle. The part 0 is also provided with a core, G, which passes upthrough a close-fitting aperture, H,

the mouth-piece, and bringing it in communi-' cation withthc air-chamberand discharge-aperture.

The casting is effected by pouring the material out of which the whistleis to be made into the mold through the opening S in the top of themold, and when it has sufficiently hardened therein it is removedtherefrom by taking off part A, so as to withdraw core D from out of themouth-piece, when the whistle is lifted from off the core G by thelifting of part B; or the same can be done by withdrawing core G withpart 0 from out of the body of the whistle. It is evident that core Gmay be directly attached to part B instead of to part 0, as abovedescribed, and in which case the whistle would be merely lifted from offcore G and out of part B, in which case the part 0 might or might not beused, as desired; but this would be only a modification of the moldbefore described, and of the way of relieving the whistle from the moldand cores, because the principle is the same, and I only prefer theformer in order that the whistle need not be on its exterior of onlysuch a form that would admit of its being delivered by the latter, butinstead thereof of any desired exterior. The acoustic principle of thiswhistle is that familiarly illustrated by blowing into a key or a bottleso as to produce a whistle.

Having described my invention, I claim as new and desire to secure byLetters Patent The whistle-mold, provided with cores D and G, allconstructed and operated substantially as herein set forth.
